- Nóta At seeps, a recent review of existing data estimated that 0.02 Gt of methane-C is consumed annually in the sediment, with an additional 0.02 Gt methane-C escaping annually into the hydrosphere. Both vents and seeps transmit chemical and heat energy to the water column via plumes. At seeps, however, the vast majority of energy is trapped within the seafloor.At both vents and seeps, complex structures are created by animals, but the most extensive and enduring substrata are large sulfide chimneys at vents and extensive pavements of carbonates at seeps. These surfaces are often colonized by 'background' fauna, which use them as attachment substrata, shelter, and for access to food via grazing or by positioning themselves in the current.
